Meteorological impact on gravimeter and seismometer readings

Background. The density of atmospheric air varies with temperature. Therefore, variations in the layer temperature leads emergence local gravity anomalies. amplitude such anomalies can exceed ±0.1 mGal. results obtained by Arti Geophysical Observatory(Yekaterinburg, Russia) on non-tidal confirm influence gravimeter readings, which may significantly calculated data. Aim. To assess impact weather changes seismic and fields.Materials methods. At RAS Bishkek Geodynamic Test Area (Bishkek, Kyrgyzstan), Institute Geophysics (Yekaterinburg, Zapolye Observatory (Vladimir, Russia), was measured CG-5 AUTOGRAV gravimeters. Shults Cape (Vladivostok, BFO (Black Forest, Germany [10]) observatories, gravimetric measurements were conducted La Coste & Romberg tidal Results. Variations found to lead Conclusion. Meteorological processes, as liquid-water content Earth’s temperature, affect readings gravimeters seismometers. Along seismometers are affected pressure, humidity water atmosphere. This is related deformations under Moon Sun. Meteor streams their atmosphere have greatest
